IMPROVEMENT IN GRlNDlNG-MILLS.

Specification forming part of Letters Patent No. 183.139, dated October 10, 1876; application tiled June 20, 1876.

'taken on the line .fr m, Fig. 2. Fig. 2 is a plan view.

Similar letters of reference indicate corresponding parts.

A is the grain-hopper; B, a shoe, by which the grain is fed onto a sieve, D, Where it is subjected to a blast from the fan E, to sepa- The sieve and the feed-shoe B are shaken by the crank F on the fan-shaft and connecting-rod G. From the sieve the grain falls down the chute H into the feed-hopper I, which is as Wide as the length of the stones, and has corrugations J in the bottom to effect equal distribution of the grain along the stone from end to end. K represents driving-belts to each end of the running-stone L, both being from the countershaft M, which is so located that the pull of the belts is directly against the crowding of the journals oi' the runner against the boxes by the grain. N represents the adjustingscrews to the bedstone O, which I mount in the spring-supports R, so as to allow the stone to yield or spring back a little when necessary.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the driver of a grinding-mill composed ot' a cylindrical ruimer and a concave, of driving-belts K, one at each end of the driver, said belts being led in a direction opposite to the push of concave to a counter-shaft, M, as and for the purpose set forth.
